The long wait for nine winners of the Young American Medal for Bravery is finally to end Sept. 11 at the White House.

The youngsters selected over the past five years to receive the heroism awards are to be recognized then by President Reagan.

President Carter never found time to schedule the event, despite periodic pleas from the Justice Department officials who ran the program. Under the legislation that set up the program, the president must present the awards.

Donna Slack, 20, for instance, is a Michigan college student who was told three years ago that she would be recognized for rescuing three boys during a tornado in 1976. "I didn't mind at all that it was late," she told the Associated Press. "I never thought it would come true."

The program calls for the winners and their parents to be flown to Washington for the ceremony. Jerome Dale, 17, of Baltimore, who rescued two children from a fire in 1979, was told that a limousine would be sent for him and his mother. He said he'd rather fly because he'd never been on a plane, so officials are trying to arrange a hop from Baltimore-Washington International Airport to Washington National Airport.

"There's nothing too good for a hero," one Justice official said.
